Estimated due date mu adalah around 25 April 2022 lah, kalau LMP mu 29-07-2021. Biasanya kira 40 weeks dari hari pertama period, so that's roughly 9 months dari July ke April. Tapi tentu saja confirm dengan doctor mu kay, sebab sometimes dates boleh adjust sikit based on scan results, especially kalau irregular cycle. Good luck with your pregnancy!
